claslite modules in GRASS?

I'm wondering if any GRASS users have been able to adapt a similar
workflow of Claslite within GRASS GIS.

http://claslite.ciw.edu/

Claslite is a suite of remote sensing modules developed by Carnegie
Institution for Science for rapid assessment of forest cover using
various satellite platforms. Unfortunately, the software is not FOSS
but is it possible to adapt the developed tropical forest spectral
library within GRASS?

From their web page:

"... system to convert satellite imagery from its original (raw) format,

-> r.in.gdal

" ... through calibration, .."

-> r.mapcalc

"... pre-processing ..."

-> r.mapcalc

"... , atmospheric correction, "

-> i.atcorr

"... and cloud masking steps"

-> r.mapcalc with TIR channel(s)?

" and then performs a Monte Carlo Spectral Mixture Analysis ..."

-> I had once written i.spec.unmix (GRASS Addons SVN), Monte Carlo stuff
is available in R (spgrass6 interface).

So, quite some pieces seem to be there.

Follow-up inquiry, how do grass use spectral libraries in image
classification? Google couldn't give any result except for Markus's
paper related to i.spec.unmix
